Louisiana corrections officials are asking a federal appeals court to overturn a ruling that would require disclosure of the seller and manufacturer of the state's execution drugs.

Judge James Brady ruled last week that the corrections department must reveal this week the information about where it obtained its two lethal injection drugs.

Instead of revealing the details, a lawyer for the Department of Corrections and the Louisiana State Penitentiary filed a notice of appeal Tuesday and asked to keep the information secret while the appeal is pending.

State officials say if they identify how they're getting the drugs, they could have trouble buying more because companies don't want to be known as helping facilitate an execution.

Brady said corrections officials failed to offer proof of their claims.
